Resquested tools/access, how to get them?

Hey there,
I built an agent with natural language. It’s supposed to search trends in web searches and social media, write articles about what’s trending and then post them on a wordpress installation. However, it doesn’t publish them despite having set up the proper secrets :

WP_BASE_URL
WEBHOOK_SHARED_SECRET
WP_APP_PASSWORD
WP_USERNAME

It keeps requesting for tools or http access… either a Wordpress REST API tool or an HTTP access to send the articles via webhooks. It has all the information it needs to do the job, but apparently can’t do it until it gets a tool or access from somewhere else. I asked the AI who to contact to get HTTP access, and it said my workspace admin. However, this is a single member free instance, there is no admin and I don’t get any request for http access when the AI tells me it has asked for it.

How do I get this started to send the articles via webhook or REST API?
